1. A communication device, comprising: transmission and reception circuitry configured to communicate with an external communication device; and control circuitry configured to cause the transmission and reception circuitry to transmit a recovery signal including a first command, wherein in a case where the external communication device is out of working order, the recovery signal restores communication with the external communication device, in a case where the external communication device is in working order, the recovery signal prescribes that no restoring is to be executed in the external communication device, the transmission and reception circuitry is configured to communicate in at least a Standard Data Rate (SDR) mode and a High Data Rate (HDR) mode, data communication being performed at a first transfer rate in the SDR mode and being performed at a second transfer rate higher than the first transfer rate in the HDR mode, and the recovery signal includes a second command, the second command prescribing the external communication device to terminate the HDR mode.
A communication device includes transmission and reception circuitry for communicating with an external device and control circuitry that generates a recovery signal containing a first command. If the external device is malfunctioning, the recovery signal restores communication. If the external device is functioning normally, the recovery signal instructs the device to skip restoration. The device supports both Standard Data Rate (SDR) and High Data Rate (HDR) modes, with SDR using a lower transfer rate than HDR. The recovery signal also includes a second command that forces the external device to exit HDR mode, ensuring reliable communication.

The recovery signal ensures compatibility and reliability across different data rate modes, preventing disruptions in data transmission.
2. The communication device according to claim 1 , wherein the first command is a broadcast command.
A communication device is designed to improve data transmission efficiency in wireless networks by optimizing command handling. The device includes a processor and a transceiver configured to receive a first command from a network node. The first command is a broadcast command, meaning it is intended for multiple devices rather than a single recipient. The processor processes this command to determine whether the device should respond or ignore it based on predefined criteria, such as device status or network conditions. This selective response mechanism reduces unnecessary transmissions, conserving bandwidth and power. The device may also receive a second command, which is a unicast command directed specifically to it, and processes this command accordingly. The transceiver then transmits a response to the network node based on the processed commands. This system enhances network efficiency by minimizing redundant communications while ensuring critical commands are properly handled. The invention is particularly useful in dense wireless networks where broadcast traffic can overwhelm available resources.
3. The communication device according to claim 1 , wherein the recovery signal includes a third command following the second command, the third command declaring a termination of communication.

The response signal indicates whether the external device has successfully recovered or remains out of working order. The communication device further includes a parity checker that verifies the integrity of commands exchanged with the external device, including commands other than the recovery signal, to determine whether the external device is in working order or out of working order. The parity check ensures that data transmission errors are detected, allowing the communication device to assess the operational status of the external device based on command integrity rather than relying solely on the recovery signal. This system improves reliability in communication by distinguishing between temporary communication failures and persistent faults, enabling more accurate recovery actions.
8. The communication device according to claim 1 , wherein, in the case where the external communication device is out of working order, the recovery signal causes the external communication device to ignore subsequent communication.
A communication device is designed to manage communication failures with an external device. The device detects when the external device is malfunctioning or unresponsive and transmits a recovery signal to address the issue. The recovery signal instructs the external device to disregard any subsequent communication attempts, preventing further errors or disruptions. This ensures system stability by halting communication until the external device is restored to proper operation. The device may also monitor communication status, detect anomalies, and initiate recovery procedures automatically. The recovery signal can be customized based on the type of failure, such as a temporary glitch or a persistent malfunction. By ignoring subsequent communication, the external device avoids processing corrupted or incomplete data, reducing the risk of cascading failures. This approach is particularly useful in networks where uninterrupted communication is critical, such as industrial control systems, medical devices, or financial transaction systems. The system enhances reliability by isolating faulty devices and maintaining operational integrity until repairs or resets are performed.

The device includes a transmitter configured to send a first command to one or more other devices, a receiver to receive a response from the other devices, and a processor to determine whether the communication medium is available based on the response. The first command is a broadcast command, meaning it is sent to all devices within the network rather than a specific device. The processor analyzes the response to assess medium availability, ensuring efficient and collision-free data transmission. The device may also include a memory to store data related to the communication medium's status and a controller to adjust transmission parameters based on the processor's determination. This system helps prevent data collisions and optimizes network performance by dynamically managing access to the shared communication medium.

A communication device includes control circuitry that detects errors in data transmission. The device operates in a system where data is transmitted between devices, and errors can occur during transmission. The control circuitry is configured to detect these errors by performing a parity check on a command that is separate from a recovery signal. The recovery signal is used to restore communication after an error is detected. The parity check involves verifying the integrity of the command by checking if the number of bits set to 1 in the command matches a predefined parity value. If the parity check fails, the control circuitry identifies an error in the transmission. This error detection mechanism ensures reliable communication by identifying corrupted data before it is processed further. The device may also include additional features, such as transmitting the recovery signal to re-establish communication after an error is detected. The parity check is performed on commands other than the recovery signal to avoid unnecessary overhead and ensure efficient error detection. This approach improves communication reliability by quickly identifying and addressing transmission errors.
14. The communication device according to claim 9 , wherein, in the case where the communication device is out of working order, the recovery signal causes the communication device to ignore subsequent communication.
A communication device is designed to operate in environments where reliable communication is critical, such as industrial or medical settings.
